Overcommitment, Work-Related Behavior, and Cognitive and Emotional Irritation in Veterinarians: A Comparison of Different Veterinary Working Fields.

Mental health is a serious problem among veterinarians. The aim of this study was to analyze work-related behaviors and experience (AVEM), overcommitment (OC), and cognitive and emotional irritation (IS) in different veterinary working fields. The survey included 724 German veterinarians (average age 41.

Sociodemographic influences on private and professional contact behaviour during the COVID-19 pandemic in Germany: cross-sectional analysis based on a Regional Blood Donor Cohort.

Objective: The COVID-19 pandemic has had significant health and socioeconomic impacts worldwide. Extensive measures, including contact restrictions, were implemented to control the spread of the virus. This study aims to examine the factors that influenced private and professional contact behaviour during the COVID-19 pandemic.

Determining the optimal frequency of SARS-CoV-2 regular asymptomatic testing: A randomized feasibility trial in a home care setting.

Background: The SARS-CoV-2 pandemic presented a challenge for caregiving relatives in the home care setting. Caregivers can transmit SARS-CoV-2 to their relatives who are often at high risk for a severe course of COVID-19. Regular testing of asymptomatic caregivers for SARS-CoV-2 may reduce the risk of transmission.

Well-being of veterinarians in rural and urban areas.

Introduction: The field of veterinary medicine is characterized by a variety of challenging working conditions. The alarmingly low mental well-being of veterinarians has been examined from various perspectives. However, the influence of work location on the well-being of veterinary professionals has scarcely been investigated.

Physical stress and musculoskeletal complaints of veterinarians - A narrative review.

Introduction: Veterinarians have high physical workloads. The aim of this narrative review is to evaluate the literature on typical physical workloads, such as lifting/carrying and forced position (during surgery) and predictors of injuries. The health complaints of veterinarians were also examined.

Cohort profile: a longitudinal regional cohort study to assess COVID-19 seroprevalence in blood donors - baseline characteristics of the SeMaCo study participants.

Purpose: The SeMaCo study (Serologische Untersuchungen bei Blutspendern des Großraums Magdeburg auf Antikörper gegen SARS-CoV-2), a prospective, longitudinal cohort study with four survey phases spanning 3-5 months each over a period of 22 months, extends the spectrum of seroepidemiological studies in Germany. We present here a careful characterisation of the initial survey phase of the cohort to provide baseline data on infection incidence and obtained from questionnaires, focussing in particular on the attitude towards COVID-19 vaccinations, the vaccination success and the vaccination acceptance.

Participants: A total of 2195 individual blood donors from the donor pool of the blood donation service of the University Hospital Magdeburg were enrolled in the initial survey phase from 20 January 2021 to 30 April 2021.

Activation of the stress response among the cardiac surgical residents: comparison of teaching procedures and other (daily) medical activities.

Background: The aim of this Pilot study was to investigate the cardiac surgical residents' workload during different surgical teaching interventions and to compare their stress levels with other working time spent in the intensive care unit or normal ward.

Methods: The objective stress was assessed using two cardiac surgical residents' heart rate variability (HRV) both during surgical activities (32 selected teaching operations (coronary artery bypass graft n = 26 and transcatheter aortic valve implantation n = 6), and during non-surgical periods. Heart rate, time and frequency domains as well as non-linear parameters were analyzed using the Wilcoxon test.

Evaluation of Stress Levels of Trainee Cardiac Surgery Residents during Training Interventions Using Physiological Stress Parameters.

Background: This study analysed the psychological and psycho-emotional stress in cardiac surgery. Using heart rate variability (HRV) analysis, it is possible to record intraoperative objective stress responses in surgeons. The aim of the study was to assess with the help of HRV parameters the postulated increased stress levels of cardiac surgeons in training compared to experienced senior cardiothoracic surgeons in exactly the same work situation in order to make qualification-differentiated statements about physiological stress during surgical interventions.

Heart rate variability as a strain indicator for psychological stress for emergency physicians during work and alert intervention: a systematic review.

Background: The workloads of emergency physicians are severe. The prevalence of burnout among emergency physicians is higher than with other physicians or compared to the general population. The analysis of heart rate variability (HRV) is a valid method for objective monitoring of workload.

Exaggerated beat-to-beat R amplitude variability in patients with panic disorder after intravenous isoproterenol.

Background: Anxiety symptoms are associated with a marked increase in sudden cardiac death, suggesting an abnormality in cardiac autonomic function. Our previous studies show a relationship between R amplitude variability and sympathetic function.

Methods: We examined the effects of beta-adrenergic stimulation on R and T amplitude variability in panic disorder patients by infusing the beta-adrenergic agonist isoproterenol in 6 panic disorder patients and 11 normal subjects.

Efficacy of pregabalin in the treatment of generalized anxiety disorder: double-blind, placebo-controlled comparison of BID versus TID dosing.

Pregabalin is a new anxiolytic that acts as a presynaptic inhibitor of the release of excessive levels of excitatory neurotransmitters by selectively binding to the alpha2-delta subunit of voltage-gated calcium channels. The current study evaluated the anxiolytic efficacy of BID versus TID dosing of pregabalin in patients with generalized anxiety disorder. Outpatients with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition generalized anxiety disorder and having baseline Hamilton Anxiety (HAM-A) total scores > or =20 were randomized to 6 weeks of double-blind treatment with pregabalin 200 mg/d (BID; N = 78), 400 mg/d (BID; N = 89), or 450 mg/d (TID; N = 88) or placebo (N = 86).

Complex demodulation of cardiac interbeat intervals: increased cardiac sympathovagal interaction during human sexual activity.

In this study, we analyzed heart rate variability during sexual activity using complex demodulation, which is a useful technique to study continuous changes in different frequency bands over short periods of time. Complex demodulation has the advantage of having higher time resolution compared to spectral analysis. We quantified the low frequency (LF: 0.

Effect of fluoxetine, pemoline and placebo on heart period and QT variability in normal humans.

Objective: To measure the effects of fluoxetine and pemoline on heart period and QT variability.

Methods: Healthy volunteers were randomly assigned treatment with 20 mg daily of fluoxetine (n=7), 56.25 mg of pemoline (n=7) or placebo (n=9).

Approximate entropy of symptoms of mood: an effective technique to quantify regularity of mood.

Objectives: Several psychiatric conditions are associated with lability of affect. In this study, we investigated regularity of mood using APEN (Approximate Entropy) on daily subjective ratings using a Visual Analog Scale with 11 items pertaining to mood.

Methods: APEN was applied to the data in a double-blind placebo controlled investigation on the effects of fluoxetine (n=19), pemoline (n=18) and placebo (n=20) in normal controls.

Pregabalin: a new anxiolytic.

Pregabalin (S-[+]-3-isobutylgaba) was designed as a lipophilic GABA (gamma-aminobutyric acid) analogue substituted at the 3'-position in order to facilitate diffusion across the blood-brain barrier. It was originally developed as an anticonvulsant agent, however it has been shown to be effective in the treatment of several disorders including hyperalgesia and behavioural disorders. Although its exact mode of action remains unclear, pregabalin interacts with the same binding site and has a similar pharmacological profile as its predecessor, gabapentin (1-[aminomethyl] cyclohexane acetic acid).

Twenty-four-hour QT interval variability: increased QT variability during sleep in patients with panic disorder.

Recent studies on beat-to-beat QT interval variability (QTV) have shown that it can be used as a noninvasive measure of cardiac repolarization lability. It is also a predictor of sudden cardiac death and is higher in patients with anxiety and depression. This study examined the diurnal measures in QTV in 32 normal adults and 22 patients using 24-hour electrocardiogram records.

Diminished chaos of heart rate time series in patients with major depression.

Background: Depression and anxiety have been linked to serious cardiovascular events in patients with preexisting cardiac illness. A decrease in cardiac vagal function as suggested by a decrease in heart rate (HR) variability has been linked to sudden death.

Methods: We compared LLE and nonlinearity scores of the unfiltered (UF) and filtered time series (very low, low, and high frequency; VLF, LF and HF) of HR between patients with depression (n = 14) and healthy control subjects (n = 18).

Heart rate time series: decreased chaos after intravenous lactate and increased non-linearity after isoproterenol in normal subjects.

In this study, we reanalyzed our previous heart rate time series data on the effects of intravenous sodium lactate (n=9) and intravenous isoproterenol (n=11) using non-linear techniques. Our prior findings of significantly higher baseline non-linear scores (NL: S(netGS)) and significantly lower largest Lyapunov exponents in supine posture in patients with panic disorder compared to control subjects prompted this study. We obtained the largest Lyapunov exponent (LLE), and a measure of non-linearity (NL: S(netGS)) of heart rate time series.
